Après la formation initiale de prise en main du recycleur rEvo j'ai commencé à détailler la checklist officielle puis celle de Tybo pour me faire "la mienne" avec mes annotations. Ensuite Isa s'est lancée dans une checklist de son côté. Notre préoccupation étant de ne rien oublie, "de bien faire" et surtout de se dire que si on laisse passer quelques semaines sans plonger on risque de ne plus savoir comment faire certaines étapes. Au final on s'est demandé si ça ne serait pas plus futé de l'avoir sur le smartphone que sur une plaquette qu'on égare... ou trop petite et sur laquelle on aimerait bien avoir des détails (surtout quand on a "oublié" un peu après une longue période d'inactivité ou quand on débute). C'est ainsi que rEvoCheck est arrivé sur nos smartphones, quelques échanges avec la communauté plus tard et voici qu'il débarque pour tout le monde !
